[Topology.Container.Dynamic] Add class TriangleSubdividers to store methods to subdivide a triangle in differents configurations

[epernod]

Add utility class for TriangleSetTopologyModifier component.
The class TriangleSubdivider allows to split triangle following 5 possible scenarios to subdivide a triangle.

Those subdividers will be used in a new version of Triangle incision in TriangleSetGeometryAlgorithms to come in futures PR.
Examples of use can be found in Tearing Plugin in PR InfinyTech3D/Tearing#50 and InfinyTech3D/Tearing#51

Some benchmarks scenes have been introduced in those PR on several triangles configuration at start:

• 1Node subdivision (1 Node inside the triangle)
  

• 1Edge subdivision (1 Node on 1 edge of the triangle)
  

• 2Edge subdivision (1 Node on 2 edges of the triangle)
  

• 3Edge subdivision (1 Node on 3 edges of the triangle)
  

• 2Node subdivision (1 Node on 1 edges of the triangle and 1 Node inside the triangle)
  

Tests have been added for:

• testSubdivider_1Node();
• testSubdivider_1Edge();
• testSubdivider_2Edge();
• testSubdivider_3Edge();
• testSubdivider_2Node();

I definitely need a refresh on this but the CI says yes
